Patent number: 10625000Abstract: The invention relates to a method for estimating a negative pressure at a wound site during a negative pressure wound therapy. The method comprises the steps of determining a negative pressure value by means of a pressure sensor, determining a pump speed associated with the electrical pump, multiplying the pump speed by a constant to obtain a modification value, and combining said modification value with the negative pressure value determined by means of the pressure sensor to obtain a modified negative pressure value. Said modified negative pressure value corresponds to the estimated negative pressure present at the wound site. The invention further relates to a negative pressure wound therapy system adapted to execute said method of estimating a negative pressure at a wound site.Type: GrantFiled: December 23, 2016Date of Patent: April 21, 2020Assignee: Paul Hartmann AGInventors: Pierre Croizat, Jürgen Hofstetter, James Stein, Chris Dawber, Mark Hsieh
